    Human skeletal-muscle aldolase: N-terminal sequence analysis of CNBr- and o-iodosobenzoic acid-cleavage fragments.

    Abstract

    Fructose-1,6-bisphosphate aldolase was purified from human skeletal-muscle by affinity elution chromatography. Four CNBr-cleavage fragments were purified by gel filtration, and their N-terminal amino acid sequences were determined. Cleavage with o-iodosobenzoic acid at the three tryptophan residues also yielded fragments suitable for N-terminal sequence analysis. Thus, the sequence of 272 of the 363 residues was established. These sequence results allow many of the discrepancies between the two published rabbit skeletal-muscle aldolase sequences to be resolved. The human aldolase sequence reported here is 96% identical to a "consensus" rabbit aldolase sequence. A comparison with a partial sequence of Drosophila aldolase (103 residues) shows 80% identity. The determination of the amino acid sequence of human aldolase is important for the interpretation of the crystal structure of this enzyme.
